Wired Zigbee switches

Controlling smart lights from dumb switch?

Hi, I have some old wired light switches which for aesthetic reasons I want to keep. Ideally, however, I would like them to trigger Hue or other smart lights rather than turning the power on/off to dumb lights (as more complex constellations of lights become possible this way without the extra wiring). Is there any way to add a device to these switches, so that the power on/off state of the physical switch will be sent to Smartthings? Thanks
